Two identical light bulbs, each with resistance R = 2  are connected to a source with E = 8 V and negligible internal resistance. Find the current through each bulb, if the bulb in series and (ii) in parallel. ​

The sun’s mass is 2.0×10^ 30 kg, its radius is 7.0×10 5 km, and it has a rotational period of approximately 28 days. if the sun should collapse into a white dwarf of radius 3.5×10 3 km, what would its period be if no mass were ejected and a sphere of uniform density can model the sun both before and after?
